Astronomy & Space - January 2007

I'm thinking of writing a sci fi story. Humans have colonized the Jovian moons. Being humans, they create huge amounts of waste and garbage (from things imported from other planets.) They use Jupiter as a big garbage dump. How much garbage would they have to toss onto Jupiter before it becomes so massive, it turns into a star? Is this even possible- is it correct to assume that adding mass will eventually cause the planet to become a star, or are other conditions needed?

I realize that garbage might not be nearly enough to tip the scales. Do you have any ideas on what humans COULD toss into Jupiter, or cause to crash into Jupiter (like asteroids... "Let's get rid of those pesky asteroids by shoving them into the nearest planet! Traders between Earth and Jupiter always have to go around the darn things...") Is that enough mass?

I was wondering if it is possible to determine the Earths true absolute movement through space. The Earth orbits the sun at approx 30km/s and our solar system orbits the galaxy at approx 300 km/s, but movement though space if always relative to something else.

Would it not be possible to determine the Earths ABSOLUTE movement through space by taking 3 lasers and running them perpendicular to each other (X,Y,Z)? Then by measuring the red/blue shift on each X,Y,Z, would that not give the Earths true direction and speed relative to space itself? Or is that red/blue shift measurement not detailed enought? Has anyone ever tried this in the spirit of research?

i was out in the suberbs of my city at my barn, it was late at night and it was a cloudy night, the only city was a couple miles away in the opposite direction. i saw a large chunk of the cloudy sky flickering in an orange glow - it looked like something you would see in a science-fiction movie. I don't belive in aliens and i refuse to belive that it was some sort of space craft, the area of the sky was to large (maybe about 2 square acers). It was litteraly like a large fire in the sky and it was not lighting - the flickering continued for at least an hour non stop and i left before it stopped. i haven't seen it since. is there something that could make an area that large flicker like that?

If a black hole is a true singularity, then it seems that infalling matter (infalling from some accreation disc, assumibly) would have to reach superluminal velocity just to pass into the actual singularity horizon. (assuming matter is not taking a direct shot at the singularity..I don't think its possible anyway). This is a problem because it would be going backwards in time and would never actually combine with the hole itself. It would orbit, near the speed of light, but never cross? How does matter overcome the angular momentum and still obey our known laws of physics and crash the singularity border?

Do you believe creator of universe?
If yes, where are creator? inside universe or outside universe?
Are heaven and hell part of universe? If no, where are heaven and hell?
Is creator (God) in heaven? Then, who create heaven?
If God create heaven, then where are creator before heaven created?

If there is no creator in universe, then why there are big bang?
From where all the energy coming? Suddenly appear???

After all, octopi are quite alien. They have totally different respiratory, cardiovascular, reproductive, and nervous systems. They are certainly very intelligent and must have a completely foreign way of thinking because of their physiological differences.

Happy New Year all. Does anyone think that we will ever gain the technology to accel in outer space travel like old tv shows? and if we did, would any of you want to explore outer space?

I know the axis of the Earth determines the height of the moon above the horizon. Can this height be predicted whether the moon will be high in the sky or stay close to the horizon during a bright moon as it tracks from East to West?
